The growing and urgent rallying cry from people around the world to address critical global issues reached a fever pitch in 2015. From star-studded events like the Global Citizen Festival (headlined by Beyoncé, Coldplay, Stephen Colbert and others to take a stance against poverty), to the hundreds of thousands of individuals who took to the streets just two weeks ago at 2,300 separate climate marches, there's no denying a heightened level of awareness, activism and enlightenment around the world's acute social and environmental issues.
